Residential Seismic Strengthening

Residential Seimic Strengthening - HousePortland and the surrounding communities are located in a seismically active region.

Earthquakes are a natural occurrence caused by the constant motion of the Earth's crust. This motion creates the buildup of pressure along faults which is released in the form of an earthquake. Earthquakes are sudden and without warning. Strong ground shaking can cause severe damage to buildings, cracking walls, toppling chimneys or even shifting buildings off their foundation. Older buildings and homes are especially at risk because they often lack adequate anchorage to their foundation and were not designed to resist the shaking and movement expected from earthquakes today. Identifying potential hazards ahead of time, strengthening homes, buildings and utilities can reduce damage and the dangers of serious injury or loss of life from an earthquake.

The City of Portland, Bureau of Development Services has a program to help you make your home more secure in our next earthquake. See brochure #12 - Residential Seismic Strengthening - Methods to Reduce Potential Earthquake Damage for more details.
